# How to use QR codes on vehicles and fleet signage

> A code on a van, truck or car turns every journey and every car park into a measurable channel — if it is printed large enough to scan from where people actually stand.

## Short answer

Vehicle signage is the one advertising channel most businesses already pay for and never measure. A QR code on the back doors or rear panel makes it measurable: you get scans with timestamps and approximate locations, which tells you which routes, depots and parking spots generate enquiries. Point it at a quote form rather than your homepage.

## Where it gets scanned, and why that shapes the design

A vehicle is read in one of two situations, and only one of them is any use:

- **Stationary** — parked at a job, at a depot, in a car park, or in traffic. This is where essentially every scan happens.
- **Moving** — effectively never. Nobody scans a van doing 50.

That makes placement a parking question, not a driving one. The rear doors and the lower rear panel are read by whoever is behind you at a light or walking past in a car park. A code on the side is read while the vehicle is parked at a job, which is often the highest-intent moment you get: a neighbour watching work being done.

Print it large. A code read from three metres needs to be far bigger than one on a leaflet, and vehicle vinyl is not the place to economise on size. High contrast, matte rather than gloss, and away from curved panels or door seams that distort the pattern.

## What to point it at

Your homepage wastes the moment. Someone scanning a van has a specific thought — *what do they charge*, *are they available*, *who are they* — and a short quote request form answers it while they are still standing there.

| Destination | Works when |
|---|---|
| Quote request form | Trades, services, anything priced per job |
| Contact card | The driver is the point of contact |
| Booking page | You take appointments |
| Homepage | Rarely the right answer |

## Measuring it

One code per vehicle is what makes the data useful. The same code across a fleet tells you the fleet works; separate codes tell you which vehicles, routes and depots do.

Location on each scan is city-level, so you learn which areas generate interest, not which street. Over a few months that is enough to decide where to send vehicles and whether a second van in a different town would pay.

## Limits and caveats

- Location is approximate, from the network rather than GPS. It shows the area, not the parking space.
- Scan volumes are low compared with print or digital. Judge this over months, not days.
- Vinyl fades and gets dirty. A code that has lost contrast stops scanning long before it looks unreadable to you — test yours periodically.
- Check local rules on vehicle advertising, and never encourage scanning by other drivers in traffic.
- A code on a vehicle lasts as long as the wrap. Keep the destination current rather than pointing at a campaign that ends.

## Frequently asked questions

### How big should the code be on a van?

Larger than feels necessary. Scanning distance is the deciding factor, and rear-door codes are typically read from two to four metres. The print dimension benchmarks cover the sizing maths.

### Should every vehicle have the same code?

Only if you do not care which vehicle produced the result. One per vehicle costs nothing and is far more useful.

### Can I change the destination without re-wrapping?

Yes. The code is dynamic, so you can point it at a seasonal offer now and the quote form later, with the same vinyl.

### Do people really scan vehicles?

In car parks and at job sites, yes. In moving traffic, no. Expect modest numbers with unusually high intent.

### Where should it go on the vehicle?

Rear doors or lower rear panel for traffic and car parks, sides for job sites. Avoid curves, seams and anything the doors split.
